Use this page to create a multi data source. A multi data source is a data source object that provides load balancing and failover processing for database connection requests between other data source objects.
Name | Description |
---|---|
Name |
A unique name that identifies this data source object in the domain. The name must be unique among all JDBC data sources and multi data sources in the domain. MBean Attribute
(Does not apply to application modules): Changes take effect after you redeploy the module or restart the server. |
JNDI Name |
The JNDI path to where this data source object is bound. By default, the JNDI name is the name of the data source. To specify multiple JNDI names for the data source, enter each JNDI name on a separate line. Applications that look up the JNDI path will get a
MBean Attribute
(Does not apply to application modules): Changes take effect after you redeploy the module or restart the server. |
Algorithm Type |
The algorithm determines the connection request processing for the multi data source. You can specify one of the following algorithm types:

Select Targets |
Select the servers and clusters on which you want to deploy your new multi data source. The targets you select will determine the data sources you can select for the multi data source to use to handle connection requests. All data sources must be deployed on the same targets as the new multi data source. |
Name | Description |
---|---|
Select Data Source Type |
Select the type of data source that you want the multi data source to use when processing connection requests: data sources that use an XA JDBC driver or those that use a non-XA JDBC driver to create database connections. The selection you make will determine which data sources you can select for this multi data source to use. It is important that all data sources used by the multi data source use the same transaction protocol so that WebLogic Server can properly handle transaction processing. |

Add Data Sources |
Select the data sources that you want the new multi data source to use when handling connection requests. The multi data source will route connection requests to the data sources you select in the order specified in the Chosen list and according the Algorithm Type previously selected. |
